I need to find a Groebner basis for an ideal generated by 10
polynomials in 10 variables, containing 14 parameters (10 of which are
constant terms). Is that within Maple capabilities? I have Maple 10
running for a couple of days now, with no result so far. Any comments

  I am having a strange problem in my Maple code.
I create a list like this:
l := [];
for i from 1 to 10 do

I am trying to figure out the w-plane of f(z)=c^z for various values of c in
C and I am having a heck of a time.
Certain things are immediately obvious:
1) If c=0, then the entire (punctured) z-plane collapses onto the w-point

Dear Maple Gurus,
I am using Maple 8.00 .
I have a system of 3 coupled 1st-order ode's I am trying to solve. I know
how to do that. However, looking at dsolve under Help I saw that it was

I got Maple 7
I wanted to calculate the effect of a band-pass (10 kHz - 1.4 GHz) on a
periodic step-function.
Therefore I thought of

I need to diagonalize an orthogonal matrix, I'm using the jordan
function of the linalg package for this.
A:=...;
B_:=jordan(A,'P');

Question 1:
In Maple, an object of the type [a,b,c] is called a list.
and an object of the type {a,b,c} is called a set.
Is there a name for an unadorned a,b,c?  This is the

Is it possible to rotate the xtickmark labels so that they are printed
vertically?
Thanks,

I need help finding the intersection of two circles... if anyone can
help or point me in the right direction PLEASE let me know!

Any help will be great, Im trying to do a Montecarlo simulation of
correlated variables, I cant figure out how to calculate mean,
sdeviation, correlation, etc of ac, bc, dc, etc. I dont know why but I
supose the type is not an array or something like that. Can anyone tell

Can someone help me please Im trying to do a matrix operation and then
I need to get out of the matrix the numbers (i.e. I need an element fo
the matrix to do other calculations), I have no clue how to do that.

I'm having some trouble working with Units in Maple.
More specifically: the piecewise function is not working: it should  
evaluate to a temperature in Kelvin, but it won't; itremains
completely symbolic. How can I solve this? Thanks for your help.

I'm having a hard time figuring out how to perform elementary operations  
on lists/arrays in
Maple. In fact, all programmatic data-types in Maple seem to confuse me -  
I'm used to program in Perl.
